First Bugatti made its landmark 1,000bhp Veyron, then it made a convertible and called it the Grand Sport, then it put the roof back on but added 200bhp and called it the Super Sport, and now, for the car's final iteration, it has taken the roof off the Super Sport. This is the world's first 255mph hair dryer, and the staggering engineering achievement that it represents is only matched by the quality of the finishing. It's as luxurious as it is quick.

The big question, obviously, is what it feels like to drive the world's fastest convertible, in terms of its speed, its presence on the road and the responsibility that comes with driving a £2m car. How does it handle at low speeds? How intimidating is it? What does that incredible acceleration feel like? In our film, above, Mr David Green finds out.
